C.2.1
The KAPWR signal is the MPC561/MPC563 keep-alive power. KAPWR is used for the crystal oscillator
circuit, and should be isolated from the noisy supplies. It is recommended that an RC filter be used on
KAPWR, or bypass capacitors that are located as close as possible to the part.
C.2.2
VDDSYN and VSSSYN are the PLL dedicated power supplies. These supplies must be used only for the
PLL and isolated from all other noisy signals in the board. VDDSYN could be isolated with RC filter (see

EXTAL pad capacitance is C
Socket capacitance C <=1pF
Board trace capacitance C <=1pF. This should be low since the crystal must be located very close
to the chip.

Note: A filter cut off frequency of 500Hz is recommended, however this will result in a
capacitor size of 33uF using a 10 Ohm resistor. This may be too expensive or large
for the system. In this case the filter shown with cut- off frequency of 160kHz will suffice.
